Let's divide 10289858 by 853
The aim is to understand the frequency of 853 in 10289858.

Going ahead to step 1:
When dividing 1 by 853, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 853

On to step 2:
The number 853 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 853

Let's proceed to step 3:
853 goes into 102 0 times with a remainder of 102.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 102, we get 102.
Include the next digit (8) from the dividend after 102, then repeat: 1028 / 853

Let's proceed to step 4:
If we divide 1028 by 853, we get 1 and a remainder of 175.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 853 from 1028 leaves us with 175.
Fetch the next digit (9) from the dividend, attach it to 175 and continue: 1759 / 853

Advancing to step 5:
If we divide 1759 by 853, we get 2 and a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1706 from 1759 leaves us with 53.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 853

Step 6:
The number 853 fits into 538 0 times, leaving a remainder of 538.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we take 0 away from 538, we end up with 538.
Bring next digit (5) of the dividend behind the 538 and repeat the process: 5385 / 853

Moving on to step 7:
853 can be fit into 5385 6 times, resulting in a remainder of 267.
Use 6 as the next digit of our solution. 
Result so far: 1206.0
If we take 5118 away from 5385, we end up with 267.
Include the next digit (8) from the dividend after 267, then repeat: 2678 / 853

Step 8:
853 goes into 2678 3 times with a remainder of 119.
Record the quotient 3 as the next digit in the result. 
Result so far: 12063.0
If we subtract 2559 from 2678, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 9:
The number 853 fits into 1190 1 times, leaving a remainder of 337.
Put 1 as the next digit of the answer. 
Result so far: 12063.1
If we subtract 853 from 1190, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 10:
853 can be fit into 3370 3 times, resulting in a remainder of 811.
The next digit of our result is 3. 
Result so far: 12063.13
Subtracting 2559 from 3370 leaves us with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Moving on to step 11:
The number 853 fits into 8110 9 times, leaving a remainder of 433.
The number 9 becomes the next digit in our result. 
Result so far: 12063.139
The remainder is 433 after subtracting 7677 from 8110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

On to step 12:
853 can be fit into 4330 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 12063.1395
Deduct 4265 from 4330 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
853 can be fit into 650 0 times, resulting in a remainder of 650.
The next digit of our result is 0. 
Result so far: 12063.1395
The remainder is 650 after subtracting 0 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 14:
853 goes into 6500 7 times with a remainder of 529.
Use 7 as the next digit of our solution. 
Result so far: 12063.139507
Subtracting 5971 from 6500 leaves us with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 15:
If we divide 5290 by 853, we get 6 and a remainder of 172.
The number 6 becomes the next digit in our result. 
Result so far: 12063.1395076
If we take 5118 away from 5290, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 16:
The number 853 fits into 1720 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 12063.13950762
Subtract 1706 from 1720 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 12063.13950762 with a balance of 1.4e-08.
